Struve vs. Mitrione was set to be one of the top fights on the UFC 175 card. Chris Weidman vs. Lyoto Machida and Ronda Rousey vs. Alexis Davis were the headliners, and Struve vs. Mitrione was going to occur right before Rousey-Davis.

The immediate move leaves four fights on the pay-per-view portion of the card. Uriah Hall vs. Thiago Santos and Marcus Brimage vs. Russell Doane are the other fights.

Obviously at this point the main concern is Struve’s health and well-being, which is currently unknown.
